It could even just be building up to be a huge staging ground so that when a hive fleet gets pummelled and slowed (or starved of easy food) it can retreat back, resupply and then push forward. Allowing the Swarm to consume easy worlds and feed those fleets that are striking against more heavily defended sectors.
The Swarm certainly cannot overlook that thus far its opponents are adapting to fight it. Evolution and change are at the core of the Tyranid so new behaviours and approaches is critical to overcoming the defenders.
And evolving new models for games workshop to sell!
I reckon they are the great devourer and would love to see them enter the eye of terror.
